AMALGAMATOR.

in Amalgamators; and I hereby declare thel following to be a full,clear, and exact description thereof.

My invention relates to a new and useful arnalgarnator for saving theprecious metals i 1o from ores; and it consists in a rotating inclinedpan or vessel having an annular channel or groove for the ore and pulp,and formed by the outer rim of the pan and a concentric screen, saidgroove having within it a circumferential I 5` amalgamating-ring withinthe arc tiers of annular amalgamating-plates leading to a centraldischarge made in the pan, all of which I shall hereinafter fullyexplain, reference being made to the accompanying drawings, in which- 2oFigure l is a front elevation of my machine.

Fig. 2 is a sectional side view of same. 3 is a top view of the pan.

The object oi' my invention is to provide a simple and practical devicefor amalgamat- Fig.

ing, said device being adapted for light as well as heavy work.

A is a foundation i'rame, upon which is mounted at an incline a pan, B,which may be rotated by suitable means-as, for example,

3o gears b on its bottom meshing with a pinion,

a, on the end of a driving-shaft, C. The pan is mounted by means of acentral trunnion, c, hollow, as shown, providing for a central dischargeinto the underlying sluice D. Eriction-rollers lm, support the pan..Within the pan is an annular groove or/channel,e,formed by a concentricscreen, E. This screen is preferably made in sections secured betweenlugs d, whereby any section may be removed and 4o renewed whennecessary. The bottom of the groove e is rounded out,and is providedwith a suitable wearing-die, c.

F are heavy inet-al spheres lying loosely in groove e. These arecoveredywith shoes f for These spheres, in connection with such parts ofthe machine herein described as effect the result of pulverizing anddischarging the ore,i`orm the subject-inatter ci' a separate applicationnow pending in 5o the office.

G, which are copper plates for amalgamating purposes. Each tier is madein sections, the end of one section overlapping the next, and thisoverlapping is primarily adj usted in such manner, according to thedirection of revolution ofthe pan, that there may be a fall from one tothe other, as I shall further explain. These amalgamating-bands have aninclination toward the center, and this inclination is sufficientlygreater than that oi' the pan itself `to make them slope downwardly atall points, even at the lowest, whereby there may be a fall to thecenter. They may be supported in position vin any suitable way, as byannular 'rings set on edge.

the line of the circle of greatest diameter of the balls, whereby saidballs do not touch it. The operation of the machine is as follows: Theore and water are fed into the groove e andthe pan revolved.. The orepasses down to the lowest part of the groove, and there is pulverizedbythe action of the ball s, which are set in motion, and continuerolling because of the revolution of the pan and its inclination. Thefine pulp passes through the screen at such points where it rises highenough,and the precious particles arc arnalgamatcd ou the bands G. Itcontinually iiows to the central discharge over the bands G, and becauseof the revolution Vof the pan and the sectional overlapping of theamalgamating-bands it has a tendency to flow partially around, droppingoff the end of one section onto another. Such of the precious particlesc as lie on the outer edge of the body of pulp arc amalgamated by thecircumferential ring H.

Having thus described my invention, what I claimas new, and desire tosecure by Letters Patent, is-

l. In an amalgamator, the rotating pan B, mounted at an angle, andhaving a central opening or discharge, and an annular groove or channele, formed by the screen E, for the ore and pulp, in combination withsuitable amalgamating-plates, G, constructed as shown, and arrangedbetween said groove and the central discharge, substantially as hereindescribed.

In an anialgamator, the combination of I centraldischarge nat allpoint-s, lsubstantially` the rotating panB, mountedwat an angle, 1landhaving a central discharge, the concentric screen E, composed ofremovable sections located within said pan, forming between itself andthe rim of the pan an annular groove or, channel, e, for the ore andpulp, and suitabley amalgamating-plates, Gr, between said screen and thecentral discharge, substantially as,

herein described.

3. In an alnalgamator, the combination of the rotating pan B, mounted atan angle,and having a central discharge, the concentric screen E,whereby the annular groove or chan nel e for the ore and pulp is formed,andthe tiers of annular amalgamatingbandsG between the screen andcentral discharge, said bands having a downward slope toward theashre'in described. 4

4. In an anialgamator, the combination of the rotatinginclined panhaving a central discharge, the concentric screen forming the annulargroove e for the ore and pulp, andthe tiers of annularainalgamating-bands, formed each tier of overlapping sections and having-a downward slope at all points toward the central discharge,substantially as herein described.
